A world war starts in 1940 and lasts through the 1970s, fought with barbed wire and Art Deco tanks. A pandemic wipes out half the human race. Technology shuts down and for a while airplanes are a rarity. Afterwards, a highly productive reign of science is established, enforced by air power ("Wings Over the World"). It is centered in Basra, Iraq and we see bombers and drones from Iraq take over England, enforcing a "brotherhood of efficiency, and a freemasonry of science." There is no talk of ethics. Eventually the world comes to resemble a Westin atrium and lobby. Life expectancy goes up, but for hairstylists a cost disease still operates. In 2036 they are facing not a Medicare cost crisis but rather preparing the first trip to the moon.
It is noted that man is "conquering nature" and creating a "white world" and no one seems to flinch; Wells favored eugenics. Everyone becomes increasingly bug-eyed and a Luddite rebellion arises, although it seems to be barked down at the end of the movie.
